@rmarinho what version of the MAUI Dev Kit extension are you using?

[rmarinho]

v1.12.2 (pre-release)

[emaf]

@rmarinho that's the C# Dev Kit version, we also need to know what's the .NET MAUI extension version you are running.

[mauroa]

@rmarinho are you still reproducing this issue? Can you update to latest .NET MAUI and C# DevKit pre-release versions and let us know? Thanks

[emaf]

Closing as there is not enough information to investigate this.
